Frequently Asked Questions

What should I do if my Black Velvet (eggplant) plants get leaves speckled with tiny spots and a grayish webbing?

This looks like spider mites, which thrive in hot, dry weather. Rinse the underside of leaves with a strong spray, then spray insecticidal soap (or neem) every 5–7 days for 3 rounds, making sure to coat leaf undersides. Increase humidity around the plants by mulching and watering consistently to reduce mite flare-ups.

How often should I water Black Velvet during the main growing phase so the fruit doesn’t drop?

Water deeply whenever the top 1 inch of soil dries out—usually about 1–2 times per week, depending on heat. Keep soil evenly moist during flowering and fruiting; eggplant will drop buds/young fruit if the soil swings between wet and dry. Apply water at the base and use mulch to hold moisture, targeting consistent moisture through the 50-day season.

How can I tell when Black Velvet is ready to harvest?

Harvest when the fruits are glossy dark purple/black and firm, typically about 50 days from transplanting (or near your packet’s maturity). Pick fruits when they’re roughly 6–8 inches long (and still slender); if the skin looks dull or the fruit feels soft or seedy, it’s past prime. Use pruning shears to cut the stem with a short cap of stem attached.

Velvety, near-black blooms and foliage bring a dramatic, inky allure to the garden—then reward you with peppery, bright flavor that feels vivid and alive. Black Velvet’s tender leaves and flowers offer a crisp, succulent bite with a gentle heat, perfect for adding bold color and zing to fresh arrangements and vibrant garnishes. Grow it for a fast, trailing splash of color in about 50 days, where every bloom seems to glow against deep green.

Sowing Tips

Transplant Conditions

Wait until soil reaches 50°F and nights stay above 32°F before moving outdoors.

Expert Note

For best flowering and fewer pests, sow outdoors after frost and avoid over-fertilizing (rich soil can reduce blooms).
